Started by checking the fuse. its o.k. Have found the relay for the daytime running lights. If you look under the drivers side dash, it is just above the gas peddle to the right. If the relay doesn't fix the problem you need to look for the module. The module is under the bumper in front of the drivers side front tire. A picture of a similar module can be found at http://www.fordf150.net/howto/drl.php
Will update when it is fixed
You should note that if you are in Canada, the Daytime Running Lights are MANDATORY on all vehicles sold in Canada since 1990, and disabling them may cost you a LOT of money in fines, as disabling them is against Federal law and the Highway Traffic Acts of most Provinces.
